Florida Real Estate Practice Question

An investor incurred a 15% loss when she sold a 5-acre commercial tract (Tract A) for $680,000. She also owns a 15-acre residential tract (Tract B) for which she originally paid $1,500,000. How much must she sell Tract B for in total if she wishes not only to recover her financial loss from Tract A, but also to realize a 20% profit on her original investment in Tract B?
